Welcome to Henan San Kuang Machinery Technology Co., Ltd. Since our establishment, we have been dedicated to providing reliable and efficient mining equipment solutions. Our Horizontal Screen Scroll Centrifuge for Fine Coal Dewatering is designed to meet the demanding needs of modern coal preparation plants. With advanced technology and robust construction, this centrifuge offers exceptional dewatering performance, reducing moisture content in fine coal to as low as 8-12%, significantly improving product quality and transportation efficiency.
This equipment combines a horizontal screen scroll mechanism with a high-speed rotating drum, ensuring continuous and efficient separation of solid and liquid phases. It is ideal for processing fine coal particles (0.15-6mm) from dense medium circuits, froth flotation concentrates, or other dewatering stages. The machine's compact design and low maintenance requirements make it a cost-effective choice for mining operations of all scales.
Key Features & Benefits
- High Dewatering Efficiency: Achieves low moisture content (8-12%) in fine coal, reducing drying costs and improving calorific value.
- Continuous Operation: Scroll design ensures uninterrupted material discharge, maximizing throughput and minimizing downtime.
- Durable Construction: Wear-resistant materials (e.g., stainless steel, ceramic lined) prolong service life even in abrasive coal slurries.
- Easy Maintenance: Accessible screen panels and scroll sections simplify replacement and cleaning.
- Energy Efficient: Optimized drive system reduces power consumption compared to traditional vacuum filters or centrifuges.
- Customizable Configuration: Various screen slot sizes, rotational speeds, and motor options to match specific feed characteristics.

Application & Advantages for Fine Coal Dewatering
Our Horizontal Screen Scroll Centrifuge is specifically engineered for dewatering fine clean coal from flotation concentrate or dense medium cyclone overflow. It replaces traditional disc filters or screen bowl centrifuges with higher efficiency and lower operating costs.
- Lower Moisture Content: Achieves 8-12% moisture, reducing thermal drying load and saving energy.
- Higher Recovery: Minimizes loss of fine coal in effluent compared to conventional systems.
- Compact Footprint: Requires less floor space than equivalent vacuum filter systems.
- Adaptable to Variable Feed: Handles fluctuations in feed density and solids concentration without performance sacrifice.
